When your favorite baseball team wins, it's hard not to get excited — especially if you're right there in the stadium. It's even better when a player tosses the ball to fans. But sometimes, in the heat of the moment, things can go awry.

That's what happened during a recent game at New York's Yankee Stadium. After catching the ball that ended the game in an 8-2 Dodgers win, Los Angeles outfielder Yasiel Puig tossed it into a cheering crowd of supporters. “I saw it coming at me and I remember thinking, 'I don't have a glove to catch this ball,'” Dodgers fan Alyssa Gerharter told the New York Daily News. “I felt it hit me and I could feel immediately with my tongue there's a hole. And I looked down at my hand and saw there's a tooth in my hand.”

Ouch. Just like that, one fan's dream became… a not-so-good dream. But fortunately for the 25-year-old software engineer, things went uphill from there. Ushers quickly escorted her into a first-aid room at the stadium. She was then rushed to a nearby hospital, where the upper front tooth was re-inserted into her jaw. After a follow-up appointment at her dentist's office the next day, Gerharter said she remains hopeful the re-inserted tooth will fuse with the bone, and won't require replacement.

We hope so too. And in fact, she has as good a chance of a successful outcome as anyone, because she did everything right. If you're not sure what to do about a knocked-out tooth, here are the basics:

locate the tooth, handle it carefully (don't touch the root surface), and if possible gently clean it with water

try to open the person's mouth and find the place where the tooth came from

carefully re-insert the tooth in its socket if possible, making sure it is facing the right way

hold the tooth in place with a soft cloth as you rush to the dental office or the nearest urgent care facility

if it can't be replaced in its socket, place the tooth in a special preservative solution or milk, or have the person hold it between the cheek and gum (making sure they won't swallow it) — and then seek immediate care at the dental office

follow up at the dental office as recommended

In general, the quicker you perform these steps, the more likely it is that the tooth can be preserved. How quick is quick? The best outcomes are expected when re-implantation occurs in no more than five minutes. So if you're in this situation, don't wait: get (or give) appropriate first aid right away — it just might save a tooth!
